<p>PURPOSE:To provide a toner for developing an electrostatic charge image having very satisfactory dispersibility of wax, satisfactory fixability, anti-offsetting property, blocking resistance and developing property. CONSTITUTION:This toner for developing an electrostatic charge image contains at least a bonding resin obtd. by mixing a resin (A) having 2,000-20,000 number average mol.wt. (Mn), 4,000-50,000wt. average mol.wt. (Mw) and <3.5 ratio of Mw to Mn with a resin (B) having >=300,000 Mw in (50:50)-(90:10) weight ratio of A:B, further mixing the resulting resin mixture with wax having 75-125 deg.C m.p. and <=200cPs melt viscosity at 140 deg.C in a solvent and removing this solvent.</p> |
